CHARLES G. HUTOHINSON, OF CHICAGO, ILLINOIS.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 285,488, dated September 25, 1883.

Application filed March 8, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES G. Huron- INsoN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following, in connection with the accompanyingdrawings, is a specification.

In the drawings, Figure 1 is a vertical central section of the upper part of a bottle containing a stopper embodying my invention, showing the stopper in position for closing the neck; and Fig. 2 is alike representation, showing the bottle opened.

Like letters of reference indicate like parts;

A represents the bottle. 13 is the valve or stopper proper. The valve in the example shown consists of a rubber disk, a, arranged between two metallic disks, a and a, the latter or lower one of which is 'larger than the disk a, but not so large as the disk a. The diameter of the disk a should be such'as to permit the stopper to be pushed down through the neck, and such as to cause the edge of the disk a to be pinched by the neck sufficiently to prevent the valve from being drawn out by raising the stopper, it being understood that the diameter of the disk at is great enough for that purpose. The disk to, by having a diameter much less than that of the disk a, permits the edge of the latter to be raised so that the valve may be thrust below its seat.

I am aware that the bottle and valve herein shown and described have heretofore been combined so as to operate together in the manner now set forth; but the essential features of my present invention are those which retoits closed position with facility by means of a small hook, and that it may be easily opened by pushing it downward sufficiently for that purpose.

The disk a may be applied by being punched out at its center for being passed down upon the stem 0, and,-after being pushed down to the disk a, the disk a may be stretched over the upper metallic disk, it being understood that the arms D D are to be applied afterward.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- An internal bottlestopper in which the valve is provided with a central vertical stem extending above it and made in two parts, one consisting of the central wire or stem, 0, and the other of a bow-shaped wire attached at the concayity of its bow-shaped part to the upper end of the part 0, and forming laterally-yielding depending arms D D, having free or loose lower ends, substantially as shown and described, and for the purposes set forth.

CHARLES G, HU'IGHINSON.
